Scandium-aluminum baseball bats

Tom holds up the scandium-microalloyed aluminum bat case as the highest-strength aluminum alloy he knows of — 100 KSI yield from fine grain size achieved by extrusion-quenching. Limited to ~2 mm wall thickness; bats break and must be replaced; $300-400 retail.

This doesn't give you the 8000 series alloys. 8000 series is sort of a catch-all — that's where your aluminum-lithium alloys are. I'll have to bring in tomorrow one of the highest-strength aluminum alloys, actually the highest strength I know of. Does anyone know what the application is? They would be 8000 series. Baseball bats. Aluminum bats.
